TPSX-12 is a filter pressed, high-temperature, water-resistant calcium silicate insulation manufactured and sold through our nationwide network of distribution partners. Third-party verified to meet or exceed all physical property requirements of ASTM C533 Type I.

Calcium Silicate insulation is engineered to protect industrial piping and equipment operating continuously at temperatures up to 1200℉ (650℃). Contains integral inorganic silicate chemistry to inhibit corrosion under insulation (CUI). The filter pressing process provides on average twice as much compressive strength vs. the ASTM minimum requirement and is much stronger than North American molded calsil. TPSX-12 is calsil, only better.
